UCF Ahangari Physiology Exam #3
2025/2026 Exam Questions and Answers
| 100% Solved
Function of Blood - 🧠ANSWER ✔✔- Transportation of respiratory gases,
hormones, metabolites and nutrients
-Regulation (hormonal and temperature)
-Protection through clotting and through immune function of blood.
Hematocrit - 🧠ANSWER ✔✔The percentage of blood volume that consist of
RBC
Males: 42-52%
Females: 37-47%
,Blood - 🧠ANSWER ✔✔specialized connective tissue which contains cellular
and liquid components.
Blood cells or formed elements
Plasma- fluid portion
Blood Plasma - 🧠ANSWER ✔✔straw-colored, sticky fluid portion of blood.
-90 % water
-Na, nutrients, waste, protein, enzymes, antibodies, and hormones.
Types of Plasma proteins - 🧠ANSWER ✔✔albumins, globulins, fibrinogen
Albumin - 🧠ANSWER ✔✔60-80%
-produced by liver.
- provide osmotic pressure needed to draw water from other tissues to
capillaries.
- controls body fluid.
- excess leads to edema.
Globulins - 🧠ANSWER ✔✔-alpha, beta, gamma
,-alpha and beta produced by liver, transport lipids and fat soluble vitamins,
function in immunity.
- Gamma is important for treatment for hepatitis. prevent s/sx.
Fibrinogen - 🧠ANSWER ✔✔-important for blood clotting
-produced by liver
-fluid formed from clotted blood= serum
Blood cells (formed elements) - 🧠ANSWER ✔✔erythrocytes, leukocytes,
platelets
Erythrocytes - 🧠ANSWER ✔✔-function is to transport oxygen and carbon
dioxide
leukocytes - 🧠ANSWER ✔✔- function is to move to sites of infection
through diapedesis or extravasation.
2 types of leukocytes - 🧠ANSWER ✔✔agranulocytes and granulocytes
Agrunolocytes - 🧠ANSWER ✔✔lymphocytes and monocytes
Lymphocytes - 🧠ANSWER ✔✔mount immune response by direct cell
attack. T and B cells!

, Monocytes - 🧠ANSWER ✔✔phagocytosis and develop into macrophages in
tissues
Granulocytes - 🧠ANSWER ✔✔neutrophils, eosinophils, basophils
Neutrophils - 🧠ANSWER ✔✔phagocytize microorganisms (bacteria)
Eosinophils - 🧠ANSWER ✔✔turn off allergic response and kill parasites
Basophils - 🧠ANSWER ✔✔release histamine and other inflammatories.
RBC life span - 🧠ANSWER ✔✔-120 days
- aged RBC removed from blood in sinuses of spleen and are degraded.
Erythropoietin - 🧠ANSWER ✔✔- Hormone
- cellular O2 deficiency is initiating event in production and release of
hormone erythropoietin.
- produced in glomeruli of Kidney, mainly in liver.
-Stimulates RBC production in red bone marrow
Hematopoiesis - 🧠ANSWER ✔✔- blood cell formation
- give rise to blood cells originating in yolk sac of human embryo then to
liver of fetus. stem cells then migrate to bone marrow.
