Describe the composition and explain the functions of blood plasma

Answer explanation

Blood plasma is composed of water, electrolytes, proteins, hormones, and waste products. It functions to transport nutrients, hormones, and proteins, maintain blood pressure, and regulate body temperature.

Name the primary hemopoietic tissue and the kinds of blood cells produced

Answer explanation

The primary hemopoietic tissue is bone marrow, which produces red blood cells, white blood cells, and platelets. These cells are essential for oxygen transport, immune response, and blood clotting.

State the function of red blood cells, white blood cells, platelets

Answer explanation

Red blood cells transport oxygen, white blood cells defend against infections, and platelets aid in blood clotting. Each type plays a crucial role in maintaining overall health and homeostasis.

Name the five kinds of white blood cells and describe the function of each

Answer explanation

The five kinds of white blood cells are neutrophils (fight infections), lymphocytes (adaptive immunity), monocytes (clean up debris), eosinophils (combat parasites), and basophils (involved in allergic reactions).

State what platelets are, and explain how they are involved in hemostasis

Answer explanation

Platelets are small cell fragments in the blood that play a crucial role in hemostasis, the process of stopping bleeding. They adhere to damaged blood vessels, aggregate to form a plug, and release chemicals that promote clotting.

Describe the three stages of chemical blood clotting

Answer explanation

The three stages of chemical blood clotting are: 1) Vascular spasm, where blood vessels constrict; 2) Platelet plug formation, where platelets adhere to the site; 3) Coagulation, where fibrin forms a stable clot to seal the wound.

Explain the ABO and Rh blood types

Answer explanation

ABO blood types are determined by the presence of A and B antigens on red blood cells: A, B, AB, or O. Rh factor indicates the presence (+) or absence (-) of the Rh antigen. Together, they define an individual's blood type.

Understand the different diagnostic blood test

Answer explanation

Diagnostic blood tests help identify diseases, monitor health, and assess organ function. Common tests include CBC, BMP, and liver function tests, each providing specific insights into a patient's health status.

• 150 days

What percentage of white blood cells are neutrophils?

• 60-70%

• 20-25%
