Study Notes
Blood Vessels
- The tunica media layer is made up predominantly of smooth muscle.
- The tunica media is the thickest in elastic arteries.
- The inner layer of the blood vessels is called the tunica intima.
- The outer layer of the blood vessels is called the tunica externa.
Blood Cells
- Neutrophils are responsible for phagocytosis and play a key role in inflammation.
- Platelets are responsible for blood clotting.
- Monocytes serve as precursors for macrophages.
- Eosinophils are responsible for inducing and maintaining inflammation in allergic reactions and asthma.
- Basophils play a key role in allergic reactions.
- Lymphocytes are responsible for specific immune responses.
- Red blood cells (erythrocytes) are produced in the bone marrow and have a life span of 120 days.
Leukocytes
- Neutrophils have a multilobulated nucleus.
- Lymphocytes have a round nucleus surrounded by a thin to moderate rim of cytoplasm.
- Monocytes have a kidney bean-shaped nucleus.
- Eosinophils have a bilobulated nucleus.
- Basophils have a U-shaped nucleus.
Hemostasis
- Platelets play a key role in hemostasis.
- Precapillary sphincters help control blood flow through the capillary network.
- Valves in small veins help prevent backflow.
Blood Formation
- During the second trimester of gestation, the principal site of blood formation is the liver.
- After birth, the principal site of blood formation is the bone marrow.
- Hemopoiesis is the process of blood formation in the human body.
- Megakaryocytes produce platelets through a process of fragmentation.
- The lineages of blood cells in bone marrow are myeloid and lymphoid.
Capillaries
- The typical diameter of capillaries is 5-10 μm.
- Fenestrated capillaries have small pores and are found in the gut mucosa and endocrine glands.
- There are three types of capillaries: continuous, fenestrated, and sinusoidal.
Arteries and Veins
- The main function of elastic arteries is to stretch and recoil with each heartbeat.
- The typical diameter of arterioles is 10-50 μm.
- The main function of veins is to return blood to the heart.
- The average adult blood volume is approximately 5 liters.
Histology
- The histology of the blood and its various components can be studied using specific stains, such as Verhoeff's stain for elastic fibers.
- The histological structure of various types of blood vessels includes the tunica intima, tunica media, and tunica externa.
