What is Human Physiology I?
In short: this course gives one-to-one online tutoring in human physiology for nursing, medicine, biomedical and life science students. A verified tutor explains cells, nerves and muscles, the cardiovascular, respiratory and renal systems, and homeostasis, with exam practice.
Human physiology is the study of how the human body's cells, tissues and organ systems work and keep the internal environment stable. Human Physiology I typically covers cells and tissues, blood, the cardiovascular system, the respiratory system and the kidneys, and is taken by students of medicine, nursing, pharmacy, biomedical science and biomedical engineering.
This online course teaches Human Physiology I one to one with a verified tutor who has studied or taught it at university level, at your pace and aligned with your own module.

What does the Human Physiology I course cover?
| Unit | Key content |
|---|---|
| Cytology | Cell structure, organelles and their functions, tissue types, membrane transport |
| Haematology | Composition and functions of blood, red and white cells, coagulation, blood groups, lymphatic system |
| Cardiovascular system | Cardiac cycle, heart sounds, ECG basics, cardiac output, blood flow, blood pressure and its regulation |
| Respiratory system | Mechanics of breathing, lung volumes and capacities, gas exchange, transport of oxygen and carbon dioxide, control of respiration |
| Renal physiology | Nephron structure, glomerular filtration, reabsorption and secretion, urine formation, micturition, principles of dialysis |
What happens during the cardiac cycle?
| Phase | What happens | Valves |
|---|---|---|
| Atrial systole | Atria contract, topping up ventricular filling | AV valves open |
| Isovolumetric contraction | Ventricles contract, pressure rises with no ejection | All valves closed (first heart sound) |
| Ventricular ejection | Blood is ejected into the aorta and pulmonary artery | Semilunar valves open |
| Isovolumetric relaxation | Ventricles relax, pressure falls | All valves closed (second heart sound) |
| Ventricular filling | Blood flows from atria into ventricles | AV valves open |
How does the kidney form urine?
- Glomerular filtration: blood plasma is filtered into Bowman's capsule.
- Tubular reabsorption: glucose, amino acids, salts and most water return to the blood, mainly in the proximal tubule.
- The loop of Henle creates a concentration gradient in the medulla.
- Tubular secretion: wastes and H⁺ ions are added to the filtrate.
- ADH and aldosterone adjust water and sodium reabsorption in the collecting duct.
- The final urine passes to the bladder.
What does a worked physiology calculation look like?
Here is a typical question: a person has a heart rate of 70 beats per minute and a stroke volume of 70 mL. Calculate cardiac output.
| Step | Working |
|---|---|
| Formula | Cardiac output = heart rate × stroke volume |
| Substitute | 70 beats/min × 70 mL/beat |
| Result | 4,900 mL/min, about 4.9 L/min |
Where do students lose marks in Human Physiology?
Students most often lose marks in Human Physiology through the habits below. Each is easy to fix with practice and feedback on your own work.
| Mark-loser | What to do instead |
|---|---|
| Systems described in isolation | Link systems through homeostasis |
| Negative and positive feedback confused | Give a clear example of each |
| Units missing in calculations | Show units at every step |
| Diagrams unlabelled | Label structures and flow direction |
| Mechanisms described vaguely | Explain each step in sequence |
How is it assessed, and how can a tutor help?
Physiology modules are usually assessed by written exams with short and long answers, labelled diagrams and multiple choice, plus practicals and lab reports.
Tutors explain concepts, work through practice problems with you and give feedback on your approach. Graded work you submit must be your own, as set out in our academic integrity policy. For deadline-driven guidance, see assignment help.
How the lessons work
Lessons are live and one to one on video with screen sharing and a shared whiteboard. You can follow a full course or book sessions on the topics you find hardest before exams. See also Engineering Biomedical Physics, our Pharmacology subject page and Nursing.
Human physiology tutor online: who this course is for, prerequisites and study plan
A human physiology tutor online teaches you how the body's systems work through live 1-to-1 lessons, using diagrams, graphs and calculations from your own course, so you can explain mechanisms rather than only memorise facts.
This course suits nursing, allied health, biomedical science, pharmacy and pre-medical students taking a first human physiology module.
Prerequisites: basic biology, basic human anatomy and general science.
Course length: 36 lessons across 5 modules.
| Stage | Module | What you can do afterwards |
|---|---|---|
| 1 | Cytology | Explain membrane transport and resting membrane potential |
| 2 | Haematology | Describe blood components, clotting and blood groups |
| 3 | Cardiovascular system | Explain the cardiac cycle and calculate cardiac output |
| 4 | Respiratory system, renal function | Read the oxygen dissociation curve and explain urine formation and GFR |
Where it leads: students often add our Biomedical Physics course or Undergraduate Organic Chemistry.
Human Physiology I Course: frequently asked questions
What is human physiology?
The study of how the body's cells, tissues and organs work and maintain homeostasis.
What is the cardiac cycle?
The sequence of contraction and relaxation in one heartbeat.
What is cardiac output?
The volume of blood the heart pumps per minute: stroke volume × heart rate.
What is vital capacity?
The maximum volume of air you can exhale after a maximum inhalation.
What does the oxygen dissociation curve show?
How haemoglobin's saturation with oxygen changes with oxygen partial pressure.
What is glomerular filtration rate?
The volume of fluid filtered by the kidneys per minute, a key measure of kidney function.
Who takes Human Physiology I?
Students of medicine, nursing, pharmacy, biomedical science and biomedical engineering.
Can you help me prepare for my exam?
Yes. Tutors practise diagrams, explanations and past-style questions.
How much does a Human Physiology tutor cost?
The price depends on the tutor and session length. You see the hourly rate before booking, with no subscription.
Can a tutor do my assignment for me?
No. Tutors explain, guide and give feedback so you can complete your own work, in line with our academic integrity policy.
How do I calculate cardiac output?
Multiply heart rate by stroke volume; 70 × 70 mL gives about 4.9 L/min.
What is homeostasis?
Maintaining a stable internal environment through feedback mechanisms.
What is the difference between negative and positive feedback?
Negative feedback reverses a change; positive feedback amplifies it, as in childbirth.
How does an action potential work?
Sodium channels open to depolarise the membrane, then potassium channels repolarise it.
What does the nephron do?
Filters blood, reabsorbs useful substances and secretes wastes to form urine.
How is breathing controlled?
Mainly by chemoreceptors that respond to carbon dioxide levels in the blood.
What jobs can I get with physiology?
Physiology supports careers in clinical research, laboratory and diagnostic science, physiotherapy and allied health, sports and exercise science, pharmaceutical work, teaching and medical research. Many roles need a further degree or professional registration. A strong physiology foundation also helps if you later apply for medicine, nursing or physiotherapy.
Is human physiology hard?
Human physiology is demanding because you need to understand how systems work, not just memorise structures. Topics such as membrane potentials, cardiac cycles, renal function and hormone control usually need the most practice. It becomes manageable when you link each mechanism to diagrams and graphs, and your tutor uses exam-style questions to check your understanding.
Do you offer lessons in my time zone?
Yes. Lessons are online, so you can book times that suit your time zone.
Is MBBS required to study physiology?
No. You can study physiology through a BSc or MSc in physiology or biomedical sciences without an MBBS. However, in India, teaching physiology in a medical college usually requires an MD in Physiology, which comes after MBBS, or an MSc in medical physiology for some posts. Check the route for the role you want.
Can I get a human physiology tutor online?
Yes. You can learn human physiology with a 1-to-1 tutor online through live video lessons with diagrams on a shared whiteboard. Your tutor follows your module, explains the cardiac cycle, respiration and kidney function step by step, works through calculations such as cardiac output and GFR, and plans your exam revision.
