True or False?

Neutrophils, Eosinophils, and Basophils are classified as granulocytes, while Monocytes and Lymphocytes are considered agranulocytes.

Rarest type of leukocyte that functions in mediating the inflammatory response.

Most numerous, and it phagocytizes and destroys bacteria; the first line of defense un an infkammatory response

The most important cells of the immune system. most are found in lymphoid tissue; effective in fighting infectious organizms; act against a specific foreign molecule

plays roles in ending 1) allergic reactions by phagocytosing allergens 2) parastic infections by releasing parasite digesting enzyme, especially in the digestive system

True or false?

lymphocytes Forms cells of the immune system (B cells and T cells).

True or false

White blood cells function outside the bloodstream in the loose connective tissue.

_______________ is the process of forming new blood cells which begins in the early embryo and continues throughout life

Prevents backflow from the aorta to the L. ventricle

Prevents backflow from the pulmonary trunk to the R.

contains pectinate muscles

Prevents backflow from the R. ventricle to the R. atrium

contains thickest myocardium

Prevents backflow from the L. ventricle to the L. atrium

Pumps deoxygentated blood to the lungs

Receives blood from the pulmonary veins

Order the following leukocytes in order of most abundant to least abundant in blood:

closed-end vessels that contain minivalves

True or false?

Neither leukocytes nor platelets are considered "true cells;" only erythrocytes are considered "true cells."

_______________ is the process where circulating leukocytes leave the capillaries.

Blood vessels that withstand and dampen large pressure fluctuations due to the heartbeat and allows blood to flow smoothly and continuously throughout the body.

distal to elastic arteries and deliver blood to body argans; have thick tunica media with more smooth muscle and less elastic tissue; active in vasoconstriction

smallest arteries; lead to capillary beds and control flow into capillary beds via vadodilation and constriction

their tunica media contains one or two layers of smooth muscle cells

Within the medulla of the thymus, ________________ is the site where T lymphocytes gain the ability to recognize "self."

what is the function of lymph capillaries?

________________ guard against subsequent infections and prevent people from getting many diseases more than once.

Which of the following is a function of the larynx? (Mark all that apply)

True or False?

Capillaries are the smallest blood vessels in the body, with a diameter just large enough to allow red blood cells to pass through in a single file.

Spider-shaped cells that serve to strengthen and stabilize capillaries by forming a network around the periphery of a capillary are called

primary contributor to plasma osmotic pressure

Includes both antibodies and blood proteins that transport lipids, iron, and copper.

Protein involved in the clotting of blood?

Also known as thrombocytes?

Transports oxygen and a small percentage of carbon dioxide?

Part of the body's nonspecific defenses and immune system?

Collects lymph from lymph trunks

What is the order of the lyphatic vessels

true or false?

In terms of the immune system, the spleen functions to clean the blood of antigens.

True or false?

The average volume of blood in an adult human female is approximately 5-6L.

True or false?

The capillaries of the brain are continuous capillaries with endothelial cells held together with complete tight junctions...intercellular clefts are absent.

________________ provides support to the trachea and prevents it from collapsing during exhalation

_____________muscles project from ventricular walls and attach to strong bands called chordae tendinae to prevent eversion of atrioventricular valves.

Receives lymph from lower limbs, pelvic organs, and anterior abdominal wall.

list the 5 major trunks ( inferior to superior)

Lymphocytes that travel to the thymus become

true or false

The myocardium is the muscular layer of the heart wall that consists of smooth muscle arranged in circular and spiral patterns.

true or false?

Over one hundred different substances are dissolved in the plasma of blood and the composition of plasma varies continuously as cells and substances are added and/or removed from the blood.

true or false?

The pulmonary circuit includes the following heart chambers: Right atrium and left ventricle.

Which of the following is NOT a function of the nasal cavity?

Which cartilage found in the larynx anchors the vocal cords?

True or false?

the tunica media of blood vessels consists of circularly arranged sheets of smooth muscle fibers that sandwich sheets of collagen and reticular fibrils.

Which of the following is part of both the pericardium and the heart wall?

Contains reticular fibers covered by endothelial cells.

Drains lymph from head and neck regions

Which of the following regions of the pharynx are lined with stratified squamous epithelium?

Which of the following arteries is involved in vasoconstriction?

After spinning in a centrifuge, the components of blood will separate according to their densities (1. top of tube 2. middle of tube 3. bottom of tube):

true or false?

Peyer's patches (aggregated lymphoid nodules) are located in the appendix

What body system's sole function is to contain and destroy foreign pathogens or diseased/sick cells?

What are the main structures of the lymphatic system?

Specialized lymph capillaries located in the villi of the small intestines that receive chyle are called _____________________.

In vessels larger than 1 mm in diameter, a thin layer of loose connective tissue called the ____________________, lies just external to the endothelium.

T cells or B cells gain the ability to recognize a unique/specific antigen.
