Answer:

The statement is true

Explanation:

Hematopoietic stem cells give rise to myeloid progenitor and lymphoid progenitor and these two progenitors give rise to many immune cells. Dendritic cells are produced by both the progenitors and macrophages are produced by myeloid progenitor.

Both macrophages and dendritic cells are phagocytes. In phagocytosis, the foreing particles are injected by these phagocytes and they are destryoyed by the action of digestive enzymes present in these phagocytic cells.  

Macrophages are present in tissue and if they are present in blood they are called monocytes. Therefore the statement is true.

2. The vasa recta is a specialized capillary that branches from the ___________ arteriole. The blood flow in the vasa recta runs
lorasvet [3.4K]
<h2>Vasa recta </h2>

Explanation:

The vasa recta is a specialized capillary that branches from the efferent arteriole; The blood flow in the vasa recta runs parallel, but in the opposite direction to the flow of tubular filtrate within the nephron loop

  • The vasa recta capillaries are long, hairpin-shaped blood vessels that run parallel to the loops of Henle
  • The hairpin turns slow the rate of blood flow, which helps maintain the osmotic gradient required for water reabsorption
  • Absorbed water is returned to the circulatory system via the vasa recta, which surrounds the tips of the loops of Henle
  • Because the blood flow through these capillaries is very slow, any solutes that are reabsorbed into the bloodstream have time to diffuse back into the interstitial fluid, which maintains the solute concentration gradient in the medulla; this passive process is known as counter-current exchange
