Lymphoid organs limit the spread of disease by filtering and trapping microscopic pathogens, preventing them from traveling elsewhere in the body. which of the following statements correctly links a functional or structural feature with the appropriate lymphoid organ? (a) the outer cortex of the thymus consists of lymphoid follicles separated by inward extensions of the capsule called trabeculae.(b) red pulp, found in the spleen, contains macrophages that destroy old erythrocytes.(c) white pulp in the lymph nodes contains macrophages and leukocytes that filter pathogens from lymph.(d) the lymph nodes secrete hormones that produce functional t cells, which protect the body from pathogens.

(B) Red pulp, found in the spleen, contains macrophages that destroy old erythrocytes.

Explanation:

Lymphoid organs limit the spread of disease by filtering and trapping microscopic pathogens, preventing them from traveling elsewhere in the body. Red pulp, found in the spleen, contains macrophages that destroy old erythrocytes correctly links a functional or structural feature with the appropriate lymphoid organ.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
