We can't answer this question if we don't know the organism you're inquiring about.
cardiovascular, lymphatic, and nervous systems.
The 11 organ systems of the body are the integumentary, respiratory, endocrine, skeletal ,muscular, nervous, cardiovascular, lymphatic , urinary/excretory, reproductive and digestive.
The cloaca is a chamber that receives products from the digestive, urinary and reproductive systems. The cloaca serves as the sole posterior opening and is found in amphibians, birds and reptiles.
Digestive and respitory systems
No, humans do not have a cloaca. A cloaca is a single multipurpose opening for the urinary, reproductive, and digestive systems found in some animals like birds and reptiles. Humans have separate openings for these systems.
Smooth muscle tissue is located in the wall of the digestive tract.
The veins are found in the circulatory system.
They are found anywhere on the body and inside a lot of the body. If system like the respiratory tract has an outlet then it is filled with bacteria. Respiratory, reproductive and digestive systems all have these outlets. The skin has more bacteria on it than you have body cells. The only true sterile areas are the cardiovascular, nervous and immune systems.
The urethra is part of the urinary system. In females and males, the urethra carries urine from the bladder out of the body through the urinary meatus. In males, the urethra also carries ejaculate out of the body.
Smooth muscles are usually found (1. in the walls of blood vessels; (2. around hollow organs such as the urinary bladder; (3. and in layers around the respiratory, Circulatory, Digestive, and Reproductive tracts.
Not really. We can live without some organs found in the systems but not the entire system. We can live without a spleen or a gallbladder but not the systems they are part of (circulatory and digestive).
This is called mucous. It is produced by body systems which have an outlet to the outside. This means that your digestive, respiratory, urinary and reproductive systems all produce this sticky stuff. Any others produce a watery substance called serous fluid. These serous systems are always sterile and the others are not. Mucous has a job of trapping bacteria, pollen or even insects and it tries to prevent them from entering the body.
