Blood and Bodily Fluids

These flashcards cover key concepts related to blood and bodily fluids, including functions, components, and physiological processes.

Functions of Blood

Transportation, regulation, and protection.

Hematopoiesis

The process of blood cell formation that occurs in the bone marrow.

Components of Blood

Blood comprises plasma (55%) and formed elements (~45%), which include erythrocytes, leukocytes, and platelets.

Erythrocytes

Red blood cells that carry oxygen using hemoglobin and have a biconcave shape.

Platelets (thrombocytes)

Small cell fragments from megakaryocytes that help form blood clots.

Leukocytes

White blood cells that provide immune defense against pathogens.

Blood Plasma

The liquid portion of blood that transports nutrients, electrolytes, and waste.

Normal pH range of blood

7.35-7.45; outside this range can lead to serious health conditions such as acidosis or alkalosis.

Hemostasis

The process of blood clotting, which includes vascular spasm, platelet plug formation, and coagulation.

Lymph

A clear fluid derived from plasma, involved in immune defense and fluid balance.
