Passive transport occurs throughout the human body, primarily across cell membranes. This process enables substances like oxygen, carbon dioxide, and nutrients to move across membranes without the need for energy, utilizing concentration gradients. It is particularly significant in organs such as the lungs, where gas exchange occurs, and in the kidneys, where filtration takes place. Additionally, passive transport plays a crucial role in maintaining homeostasis in various tissues and cells.

Hemorrhoids occur on two different places on the human body: Internal hemorrhoids are located in the upper part of the rectum. External hemorrhoids are located in the lower part of the rectum.
Passive transport plays a crucial role in urine formation by facilitating the movement of water and small solutes across cell membranes without the expenditure of energy. This process occurs primarily through osmosis and diffusion in the renal tubules, allowing for the reabsorption of essential substances like water, sodium, and urea. By maintaining osmotic balance and concentrating waste products, passive transport helps regulate body fluid levels and electrolyte balance, ultimately contributing to efficient urine production.
Passive transport allows substances like oxygen and carbon dioxide to move freely across the cell membrane of red blood cells without the need for energy. This process helps maintain the proper balance of these gases, allowing red blood cells to efficiently transport oxygen to tissues and remove carbon dioxide from the body.

P.I.S.O.- Potassium in Sodium out facilitated diffusion, active transport , and passive transport and simple diffusion.
The function of HDL in the human body is to transport cholesterol for excretion to the liver. The function of LDL is to transport cholesterol to the liver for use.
testes
To transport blood throughout the human body.
No, diffusion is passive transport.Active transport would be when there are actual proteins and structures involved in the transportation of molecules/chemicals/etc..A sure sign is that all of these (that I know of) require ATP.An example would be the Sodium-Potassium Pump located along one's neurons which actively pumps (aka. transports) sodium and potassium back and forth across the membrane to build up potential charge. This is how "signals" are sent down neurons and around the body.
The liquid that transports things in your body is the blood.
In the human body, ipsilateral movements occur on the same side of the body, while contralateral movements occur on the opposite side.
testes
They transport oxygen to cells.
Haematopoesis occurs in the marrow of the human bone (i.e. in all bones of the human body).
Water absorption primarily occurs in the small intestine of the human body.
