There are 5 kinds of blood vessels.
Arteries are the blood vessels that take blood away from the heart.
Arterioles are the blood vessels that connect arteries and capllaries.
Capillaries are the blood vessels that connect arterioles and venules.
Venules are the blood vessels that connect capillaries and veins.
Veins are the blood vessels that take blood to the heart.
But mainly it is the capillaries veins and the arteries
Arteries carry oxygenated blood away from the heart to the body, veins return deoxygenated blood back to the heart, and capillaries connect arteries and veins, facilitating the exchange of nutrients and waste products between blood and tissues.
ARTERIES
- Transport blood away from the heart
- Do not contain valves
- Blood under high pressure and speed, blood pulses
- Structure = thick collagen (outer) and elastic fibre layers (middle), inner squamous epithelium layer
VEINS
- Transport blood towards the heart
- Contain semi-lunar valves to prevent backflow of blood
- Blood under low pressure, no pulse, blood moves (slowly) between valves with muscle contractions
- Structure = thin collagen (outer) and elastic fibre layers, inner squamous epithelium layer
CAPILLARIES
- Transport blood between tissues
- No valves
- Lower pressure than arteries, no pulse
- Movement of blood is slow to give maximum time for diffusion of substances
- Structure = single layer of squamous epithelium cells, no collagen or elastic fibres

Blood pressure is affected by constriction and dilation of?
Blood vessels. Constriction of blood vessels increases blood pressure by reducing the space for blood flow, while dilation of blood vessels decreases blood pressure by increasing the space for blood flow.
What are three parts of the cardiovascular system?
Three parts of the cardiovascular system are the heart, blood vessels (arteries, veins, and capillaries), and blood. The heart pumps blood through the blood vessels to deliver oxygen and nutrients to the body's tissues and organs.
What are the three distinct parts in the circulatory system?
The circulatory system consists of the heart, blood vessels (arteries, veins, and capillaries), and blood. The heart pumps blood through the blood vessels to deliver oxygen and nutrients to cells throughout the body and remove waste products.
What are the three components of the cardiovascular system?
The three components of the cardiovascular system are the heart, blood vessels (arteries, veins, and capillaries), and blood. The heart pumps blood through the blood vessels, which transport oxygen, nutrients, and waste products throughout the body.
