The Correct Answer and Explanation is :
he average blood volume in adult males is approximately 5.5 liters, while in adult females, it is about 4.5 liters.citeturn0search4
he color of blood is determined by its oxygen content.xygenated blood, found in arteries, is bright red due to the presence of oxyhemoglobin.eoxygenated blood, found in veins, is darker, appearing as a dull brick red.citeturn0search1
Using the provided key, here are the cell types or blood elements that fit the following descriptive statements:
- Most numerous leukocyte: . neutrophil
- Granulocytes (3): . basophil, c. eosinophil, f. neutrophil
- Also called an erythrocyte; anucleate formed element: . red blood cell
- Phagocytic leukocytes (3): . neutrophil, e. monocyte, c. eosinophil
- Agranulocytes: . lymphocyte, e. monocyte
- Precursor cell of platelets: . megakaryocyte
- Cell fragments: . platelets
- Involved in destroying parasitic worms: . eosinophil
- Releases histamine; promotes inflammation: . basophil
- Produces antibodies: . lymphocyte
- Transports oxygen: . red blood cell
- Primarily water, noncellular; the fluid matrix of blood: . plasma
- Exits a blood vessel to develop into a macrophage: . monocyte
- The five types of white blood cells: . neutrophil, c. eosinophil, d. basophil, g. lymphocyte, e. monocyte
Explanation:
lood is a vital connective tissue composed of plasma and formed elements.lasma, the liquid matrix, constitutes about 55% of blood and is primarily water, serving as the medium for transporting nutrients, hormones, and waste products.he formed elements include red blood cells (RBCs), white blood cells (WBCs), and platelets.
ed blood cells, or erythrocytes, are anucleate cells responsible for oxygen transport.heir biconcave shape increases surface area for gas exchange.emoglobin within RBCs binds oxygen, facilitating its delivery to tissues.
hite blood cells are crucial for immune defense and are categorized into granulocytes and agranulocytes based on the presence of cytoplasmic granules.
- Granulocytes:
- Neutrophils: he most abundant WBCs, acting as first responders by phagocytizing pathogens. – Eosinophils: ombat parasitic infections and play a role in allergic responses. – Basophils: elease histamine, promoting inflammation and participating in allergic reactions.
- Agranulocytes:
- Lymphocytes: nclude B-cells, which produce antibodies, and T-cells, which destroy infected cells. – Monocytes: irculate in the blood, and upon migrating into tissues, differentiate into macrophages that phagocytize pathogens and debris.
latelets, or thrombocytes, are cell fragments derived from megakaryocytes.hey play a pivotal role in hemostasis by forming clots to prevent blood loss.
nderstanding the composition and function of these blood components is essential for comprehending how the body maintains homeostasis and defends against disease.
