Falling arterial blood pressure promotes falling arterial blood pressure promotes enhanced sodium ion loss in urine vasoconstriction vasodilation enhanced water loss in urine

Atrial natriuretic peptide released by certain atrial cells in response to rising BP or volume, causes systemic vasodilation and inhibits renin, aldosterone, and ADH release. Hence, it enhances Na+ and water excretion, reducing BP and bv.  Falling arterial pressure promotes vasoconstriction and conserves Na+ and water.

white blood cells or wbc s are mainly 2 types-

1.agranulocytes

2.granulocytes

the monocytes or macrophages of agranulocytes , dendritic cells which are accessory leucocytes, and b cells which is one type of lymphocytes   identify the antigens present on the pathogen's surface. these three cells are called antigen presenting cells(apc) which are phagocytes and destroy the antigens by secreting antitoxins. besides this leukocyte is always plays vital role in the immunity of the body.

the transfer for conduction is the heat transfering from the liquid to the spoon

the transfer for convection is the heat rising from the liquid to the air

the transfer for radiation is the heat going through the sides of the cup and to the air

at least that is what i would do
