Blood is the fluid portion of the circulatory system.
The Lymphatic System collects lost fluid by blood and returns it to the circulatory system.
The kidney is a part of the Urinary System. It is not part of the Circulatory System
The cadiovascular system, sometimes called the circulatory system when it includes the lymphatic system.
Phylum Cnidaria (e.g. jellyfish, corals) have an open circulatory system. This means that their circulatory fluid, called coelomic fluid, bathes their internal organs directly in nutrients and oxygen. There is no distinction between blood and interstitial fluid in an open circulatory system.
The fluid part of the circulatory system is called blood. It consists of plasma, which is the liquid component that carries blood cells, nutrients, hormones, and waste products throughout the body.
bloodBlood is mainly composed of plasma, which contains mostly water.
Carpals aren't part of the circulatory system. They are your wristbones, and so they are part of the skeletal system.
The Lymphatic Circulatory System
Blood passes through the circulatory system.The lymph fluid is what runs through the circulatory system. This is blood that runs through the system.
The circulatory system primarily carries blood throughout the body, delivering oxygen and nutrients to tissues and removing waste products. Urine is not transported by the circulatory system; instead, it is produced by the kidneys and excreted through the urinary system. Lymph, on the other hand, is part of the lymphatic system, which is closely related to the circulatory system but serves to transport lymph fluid that helps in immune responses and fluid balance. Thus, while blood is carried by the circulatory system, urine is not, and lymph is transported through a separate system.
