Epididymis receives sperm from the efferent ductules and sends it on to the Vas deferens.
Epididymis is a structure that forms a connection between the efferent ductules and vas deferens.
Epididymis is a structure that helps in the maturation of sperm and make it functionally mature to carry out fertilization in the human female body. It stores the sperm cells. It matures the immature cells from the testis.
Epididymis is divided into three parts namely:
- Caput Epididymis: Part where sperm enters from testis directly
- Corpus Epididymis: Part where sperm gain motility
- Cauda Epididymis: Part where sperms are stored
Epididymis is an important region of the ductules present in the transportation of sperm out of the testis and towards the urethra of the male body.

Answer:
218.75 grams of protein.
Explanation:
If 2500 protein is consumed and its 35% energy is provided by protein then:
2500÷35×100 =875 kcal would be provided by protein.
As one gram of protein provide 4 kcal of energy:
875÷4 = 218.75 grams of potein would be consumed.
<em>Remeber the calories and kcal for food is same.</em>
<u>Helper t-cells</u> identify antigens and then multiply and trigger the production of other kinds of immune cells.
<h3>What are helper T-cells?</h3>
Helper T-cells are one of the main types of immune cells. They detect infections and activate other immune cells to fight the infection.
Your thymus develops helper T-cells. The thymus is a small gland in the front of your chest. The other types of T-cells include:
- Cytotoxic T-cells, which fight infections.
- Regulatory T-cells, which regulate or suppress other immune cells when needed.
- NKT-cells, which can enhance immunity in general.
<h3>What are the subtypes of helper T-cells?</h3>
When helper T-cells detect an infection, they form into one of two subtypes:
- TH1 helper cells release a molecule that activates a type of cell called a macrophage. Macrophages are specialized cells that help eliminate foreign substances from your body. TH1 cells also activate cytotoxic T-cells.
- TH2 helper cells release molecules that activate B-cells. B-cells create antibodies. They also release cells that cause coughing, sneezing or diarrhea to help your body get rid of foreign substances. This group of T-cells helps generate allergy antibodies.
