Veins and Arteries. Most people would know this =)
The two main blood vessels leading out of the heart are the pulmonary trunk and the aorta.
The two main parts are the heart and the blood vessels
The heart and the blood vessels
A closed circulatory system involves blood flow flowing away from the heart, to a body part, and then back to a heart. An open circulatory system involves blood moving loosely within the body of an organism.
skin surface (integumantary system) and the lungs (alveoli) .
Tracheids and vessels collectively are called "xylem." They are the two main types of water-conducting cells in vascular plants, responsible for transporting water and minerals from the roots to the rest of the plant.
what are the 2 sets of blood vessels
There are four main types of blood vessels in the human body. There are arteries which are elastic vessels that transport blood away from the heart. Then there are veins which are elastic vessels that transport blood to the heart. Next, there are capillaries which are extremely small vessels found within the body tissues that transport blood from the arteries to the veins. And last, there are the sinusoids which are extremely small vessels found in the liver, the spleen, and in bone marrow.
Blood vessels are the tubes that carry blood. Blood vessels include arteries, veins, and capillaries.
In flowering plants, there are two main types of vascular vessels: xylem and phloem. Xylem is responsible for transporting water and dissolved minerals from the roots to the rest of the plant, while phloem transports the products of photosynthesis, primarily sugars, from the leaves to other parts of the plant. Together, these vessels facilitate the plant's growth and nutrient distribution.
Two many functions of the circulatory system are the movement of nutrients and oxygen to the tissues, and movement of wastes from the tissues to the excretory system. The main organs are the heart and blood vessels.
There two lymphatic blood vessels on either side of the urinary bladder in pigs. These blood vessels supply blood to the bladder and urethra.
