Tubular secretion is a part of urine formation occurring within the nephrons of the kidneys. After glomerular filtration, in which fluids from the blood pass into the glomerular capsule of the renal tubule, the filtrate is subject to tubular reabsorption and tubular secretion within the convoluted tubules and collecting ducts of the nephrons.
The primary site of photosynthesis in plants is the chloroplasts. These organelles contain chlorophyll, the pigment that absorbs light energy needed for the process of photosynthesis to occur. Within the chloroplasts, photosynthesis takes place in the thylakoid membranes where light reactions occur and in the stroma where the Calvin cycle (dark reactions) take place.
The primary site of ATP synthesis in eukaryotic cells is the mitochondrion. Mitochondria generate ATP through a process called oxidative phosphorylation, which occurs in the inner mitochondrial membrane.
The primary site of heat loss from the body is the skin. Its not necessarily the head or feet. It is just the skin. "The skin is the primary site of heat loss. the circulating blood brings heat to the skin's surface, where small connections between the arterioles and the venules lie directly below the skin surface. Other heat losses occur through evaporation of sweat, through warming and humidifying of inspired air and through the elimination of urine and feces." (Fundamentals of Nursing 7th edition, Taylor, Chapter 24, page 517, 2011)
The primary bronchus that is the more likely site for an inspired object to become lodged is the right bronchus. It has a straighter alignment compared to the left bronchus.
The primary site for amino acid uptake after a meal is the small intestine, specifically the duodenum and jejunum. Amino acids are absorbed into the bloodstream through the intestinal wall and transported to various tissues for protein synthesis and other metabolic processes.

The primary site of intracellular digestion are the lysosomes.
"Primary" is often used to describe a primary tumor site.
The primary site for blood cell production is the bone marrow.
The primary site of photosynthesis in plants is the chloroplasts. These organelles contain chlorophyll, the pigment that absorbs light energy needed for the process of photosynthesis to occur.

The epididymis is the tubular structure where sperm mature and become motile. It is located on the back of each testicle and serves as a site for final sperm maturation and storage before ejaculation.
