The artery that supplies the chin and jaw region of the head with blood is the
facial artery which is a branch of the external carotid artery. All blood from the head arises from the common carotid artery wherein it is divided to internal carotid artery (major blood supply of the brain along with the basilar artery on the posterior side) and external carotid artery (major blood supply of the head other than the brain).
The external carotid artery has 8 major branches (from inferior to superior): (1) superior thyroid artery, (2) ascending pharyngeal artery, (3) lingual artery, (4) facial artery, (5) occipital artery, (6) posterior auricular artery, (7) maxillary artery, and (6) superficial temporal artery.
Attached is a simplified photo of the branches of the external carotid artery.
The essential amino acid for cats but not dogs is taurine. Taurine is an amino acid that is essential in the process of metabolizing fats. Cats need twelve essential amino acids compared to eleven needed by dogs. The deficiency of this amino acid is most diagnosed in cats ad it generally leads to blindness, deafness and heart failure in felines.
Soil composition would be best for availability of nutrients, water, and root development higher proportion of humus; lower amounts of clay and sand
Compared to the lower soil layers, the topsoil or surface soil often includes more organic matter and air but less clay. The topsoil typically has the highest concentration of plant roots and is more fertile than the other layers.
- Nutrient management includes managing the composition of the soil. Minerals, organic material, water, and air are the fundamental elements of soil. Typically, 45% of the soil is made up of minerals. 5% organic material 20–30% water and 20–30% air are used. At best, these percentages are merely generalizations.
- Numerous nutrients are found in soil, which are obtained from dead plants and animals. The plants eat these nutrients as nourishment. So soil contributes to the growth of plants by giving them sustenance in the form of nutrients.
