In medical sciences, the movement of solid particles (solute) from an area of greater to lesser concentration is called by DIFFUSION.
A random passage of particles always occurs from a place of higher concentration to another of lower concentration. This happens until the distribution of the particles is uniform. From the moment the equilibrium is reached, as exchanges of substances between two media become proportional.
The passage of substances through cell membranes involves several mechanisms, among which we can mention:
✴ Passive transport (no loss of energy)
➡ Osmosis;
➡ Simple diffusion;
➡ Facilitated diffusion.
✴ Active transport (with loss of energy)
➡ Sodium and potassium pump
✴ Endocytosis and exocytosis
➡ Pinocytosis
➡ Phagocytosis

Answer: Fibrous pericardium and Serous Pericardium
Explanation:
The pericardium can be defined as the fibroserous sac( double layered) which covers the whole heart. The gap between two layers of serous pericardium is filled with serous fluid. This fluid protects the heart from external shocks.
Fibrous pericardium
This layer is the most superficial layer which consists of dense connective tissue. This layer of the heart protects it from over filling of blood, anchors the heart to the surrounding wall.
Serous pericardium
This layer provides lubrication to the heart by resisting the friction which occurs during the various type of heart function.
Answer:
are u sure this question is correct
Answer:
The correct answer is option C-ANP (Atrial natriuretic peptide).
Explanation:
Vasoconstriction is the narrowing of the blood vessels which can stop or block the blood flow.
Vasoconstriction reduces the urine formation during stress conditions through the action of hormones like ADH (anti-diuretic hormone), norepinephrine, epinephrine and angiotensin II produced via the sympathetic nervous system.
The atrial natriuretic hormone (ANP) is a cardiac hormone produced to lower the blood pressure or reduce blood plasma through vasodilation, increased vascular permeability and increase renal excretion.
Thus, option C is the correct answer.
